@ScoreABSM can I see the dmesg?

There are big differences between the two revisions. The biggest one is, one is using Wifi/BT over USB and the other SDIO, which requires the sdio overlay. The reason for BT not working on Armbian, I have yet to figure out. Like I said before, it works on (my personal) a more minimal build; Debian GNU/Linux trixie/sid 6.12.26 #1 Sun May 4 17:50:23 EDT 2025 aarch64 BananaPi BPI-M4-Zero v2 ── DISK Filesystem Size Used Avail Use% Mounted on /dev/mmcblk2p2 29G 2.8G 26G 10% / /dev/mmcblk2p1 466M 74M 363M 17% /boot ── NETWORK Hostname: bananapim4zero Wireless: wlan0 UP 10.0.0.XX Bluetooth: hci0 AC:6A:A3:3B:D9:D6 ── SYSTEM Processor: Cortex-A53 @ 1416MHz 52°C Frequency: 1416MHz Online: 0-3 Governor: performance Memory: 3.8G 199M Entropy: 256 Uptime: 15:13:05 up 4 min, 1 user, load average: 0.01, 0.06, 0. It is hard for me to determine the reasons BT doesn't work, as the patching is very extensive. If it is even the patching? And yes I include the BT node in the overlay; https://github.com/armbian/build/blob/main/patch/kernel/archive/sunxi-6.12/patches.armbian/Add-BananaPi-BPI-M4-Zero-overlays.patch#L267 As for HDMI audio and GPU, the PR I posted a link to corrects this. In future releases and rolling (give it a day) it should now work. Although I think I need to now add my changes to the 6.14.y branch? I'll check.

@ScoreABSM Should fix part of the problem; https://github.com/armbian/build/pull/8191 As for Wifi, it works fine for me. Make sure you have an antenna attached or it may not find anything on the network to connect to. As one user already discovered;

The GPU node needs to be enabled. There has been adjustments made to the patching for 6.12.y and above, but I haven't messed with yet. Basically nodes need to be added for sound. As for Bluetooth. I haven't figured out yet why it doesn't work on Armbian. In my personal builds it works fine. I believe there is some patching or service preventing it from loading. But I can't be sure. I've put a lot of time already into the DTS to get this working on both REVS. To much time in my opinion. Anyone is welcome to do a PR and add and enable the bits if they like. Otherwise peps are just gonna have to wait till I get around to it again.

I tested Armbian 25.2.2 Bookworm Minimal / IOT on both the REV1 and REV2. Wifi worked fine in both cases.

The RTW88 driver was included for this; https://github.com/armbian/build/pull/7634 Prob needs to be ticked on in the defconfig for RK.

I'm waiting for the HDMI part of the audio patch to drop. There is currently discussion going on about the Audio in a private chat, concerning 6.12.y and up, but I haven't seen consensus yet. Once its reached, I will drop in the nodes. This could take time.

There was no official audio routing for the h616 until recently and still none yet for HDMI. As far as I know? https://lore.kernel.org/linux-arm-kernel/20241023075917.186835-1-ryan@testtoast.com/T/ I believe there is unofficial patching for it available in Armbian for 6.6.y, but I never added the required nodes to test it. This would be why there is no functional audio on the unit as of yet.

Last I checked PBOOT looks for a BOOT partition. By default Armbian uses a ROOTFS, which is probs why it can't find it.

If it's detecting more or less dram than it should, its U-Boot related. Depending on the version of u-boot there are two remedies as far as I know. Put a delay on it; https://github.com/armbian/build/blob/main/patch/u-boot/v2024.04/board_bananapim4zero/006-mach-sunxi-dram_helpers-add-delay-to-steady-dram-detection.patch For v2025.01 and above; https://lore.kernel.org/linux-sunxi/20250309063143.62859-1-jernej.skrabec@gmail.com/T/#t

Is the armbian firmware package installed? This error means the firmware is missing or not found: [ 6.382883] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.raspberrypi,4-compute-module.bin failed with error -2 [ 6.382928] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.bin failed with error -2 What carrier board are you using? If not using the RPI carrier, you may need to adjust pins to get Wifi to work. Also, make sure your eeprom is up to date.

If it should get it accepted; https://github.com/armbian/build/pull/7900

Yes. So instead of this patch; https://github.com/armbian/build/blob/main/patch/kernel/archive/meson64-6.12/board-odroidc4-reset.patch which only patches the C4 DTS, create a new patch, that patches against the "meson-sm1-odroid.dtsi". Problem solved. An example can be found in my personal repo; https://github.com/pyavitz/debian-image-builder/blob/feature/patches/amlogic/6.12/007-ODROID-general-patch-set.patch#L281

The solution here would be doing a PR and instead of adding the node to the DTS, it should be added to the DTSI "meson-sm1-odroid.dtsi" which both units "C4/HC4" would pick up. + reboot: meson64-reboot { + compatible = "meson64,reboot"; + sys_reset = <0x84000009>; + sys_poweroff = <0x84000008>; + + sd-vqen = <&gpio_ao GPIOE_2 GPIO_ACTIVE_HIGH>; + sd-vqsw = <&gpio_ao GPIOAO_6 GPIO_ACTIVE_HIGH>; + sd-vmmc = <&gpio_ao GPIOAO_3 GPIO_ACTIVE_HIGH>; + }; +
